.Zp all whom it may concern:

Be it known that we, CHARLES T B A LT and WENCESLAS GAGNE, citizens of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Harness-Stops for Looms, of which the followin is a specification, reference being had to t e accompanying drawings.

This invention relates to new anduseful improvements in looms and more particularly to a harness stop motion-therefor and the primary object of the invention. is to provide a device'of this character which will posltively stop the loom upon the breaking or snapping of one of the straps or other flexible connections used for retaining the harness frames in position.

A still further object of the invention resides in providing'an attachment which is disposed below the harness frames and upon which the latter are adapted to drop and another object resides in providing a device Which has engagement with the weft lever and slide for stopping the machine.

A still further object of the invention resides in providing a device which issimple and durable in construction, inexpensive to manufacture and one which will .be very 'eflicient and useful in operation.

With these and other objects in View, the Invention consists in the novel features of construction, combination and arrangement of (parts as will be hereinafter referred to an more particularly pointed out in the specification and claims."

In the accompanying drawings forming a part of this application, Figure 1 is a fragmentary side elevation of the machine showing our attachment applied to use thereon. ig. 2 is a plan view with parts in section. Fig. 3 is a vertical lon 'tudinal section through the attachment. i 4 is a transverse section therethro lgh. ig 5 is a perspective view of the stop rod proper.

f In describing our invention, we shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which 1 indicates the framof aloom having the harness frames 2 operatively mounted therej in, said frames being connected by. means of the straps or other flexible connections 3 to the operating levers 4 on the frame. Mounted on the breast beam 5 in the usual to be mounted or any p eferred m n r, is the li e 6..

which has cooperation with the weft lever 7 and weft hammer 8, in the usual or any preferred manner.

Our invention contemplates a means for stopping the loom almost immediately upon the breaking or snapping of one of the straps or other flexible corinectlons used for connecting the levers 4 with the harness frames- 2 and to this end, we provide aframe, first consisting of a air of standards or uprights 9. These stan ards or uprights are adapted on the floor in spaced relation to one another and immediately below the harness frames 2. v Ad'justably mounted .on the upper ends of these standards or uprights 9 are the plate-like members 10, the same being provided with slots through which extend set screws 11 engaged with the standards 9 to afford adjustability between the latter and said plate-like members. The one ends of said plate-like members are provided with bearings 12 alining with one another and which is oscillatingly mounted a longitudinaly disposed rod 13. Encircling this rod 13, adjacent the bearings 12, are the coil spring members 14, which have one of their ends engaged with the bearings 12 and the other ends thereof engaged with adjustable and removable collars 15 also mounted on the rod 13. In this manner, itwill be seen that the tension of I the springs 14 is adapted to dispose the rod 13 in a'particular direction.

The ends of the rod 13 projecting beyond the bearings 12 have adjustably and removably secured thereto the lever arms 16 which are arranged to extend in substantially horizontal planes below the harness frames 2. The free ends of these lever arms 16 are offset and provided with bearings 17 which receive' therethrough the rods 18. These rods are held in any adjusted position by means of the set screws 19 extending into the bearings 17 i and said rods 18 are 'bent intermediate'of their ends to provideja laterally extending portion, the extreme free ends of the latter being also provided with bearings or eyes 20. Disposed through. these earings 20 and adapted to extend substantially in vertical positions are the stop rods 21 which may beadjusted to extend at various heights above the bent ortions of the rods 18 and held in view 0 the provision of the adjusting nuts 22 thereon. The upper ends of said stop rods are bent are a ly as shown t and the est ous t e ends of the sameare again bent, as shown at 24 to be engaged with the weft lever 7.

From this construction it will be seen that should anyone of the straps or flexible connections 3 be broken or snapped during the operation of the device, the harness frames connected therewith will drop downwardly to rest upon the lever arms 16. The weight of the harness frames on the lever arms will whereby the machine will be stopped within one or two icks after the snapping or breaking of t e connection 3.

From the foregoing it will be seen that we have provided a simple, inexpensive and eflicient means for carrying out the objectsof the invention and while we have particularly described the elements best adapted, to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construc-' tion maybe resorted to without departing from the spirit or sacrificing any of the; principles of theinvention.

Having thus described this invention, what is claimed is 1. In a harness stop motion for looms, the combination with a loom frame, harness and filling stop mechanism; of a pair of spaced standards arranged within said frame belowthe harness, a pair of plate-f like members adjustably connected to the up per ends of said standards and inclined upwardly therefrom, ashaft extending longitudinally of the frame and mounted to os-. cillate in the uppermost endsof the inclined plate-like members, spring means in connection with said plate-like members and said;

shaft to normally retain the latter in one position, a pair of laterally extending arms adjustabl connected to the ends of said shaft an adapted to receive the harness frames thereon when the supporting stand ards of the latter become broken, and con- 'necting means between the outer ends ofsaid arms and the filling stop mechanism.

2. In a harness stop motion for looms, the

combination with a loom frame, harness and filling stop mechanism; of a pair of s aced stan ards arranged within said frame low the harness, apair of plate-like members adjustably connected to the upper ends of said standards and inclined upwardly there 7 from, a shaft extending longitudinallyfof the frame and mounted to oscillate-- in the uppermost ends of the incIinedQpIate-Iike,

members and said shaft to normally retain the latter in one position a pair of laterally extending arms adjustably connected to the ends of said shaft and adapted to receive the harness frames thereon when the supporting standards of the latter become broken, and adjustable means connecting the outer ends of said arms with the filling stop mechanism.

3. In a harness stop motion for looms, the combination ,with a loom frame, harness and filling stop mechanism; of a pair of standards arranged within the frame below the harness, plate members adjustably mounted on the upper ends of said standards and inclined upwardly therefrom, the upper-most ends of said plate members'being designed to form bearings, a shaft extending longitudinally of the frame and mounted to oscillate in said bearings, spring means in connection with said bearings and shaft to dispose the latter normally in one position, a pair of arms adjustably secured to the ends of said shaft and extending laterallyvtherefrom, and a pair of vertically extending arms adjust-ably connected with the free ends of said laterally extending arms, said vertical arms having an arcuate portion formed therein, terminating in a hook for engagement with the weft fork of the filling stop mechanism. a

4. In a harness stop motion for looms, the combination with a loom frame, harness and filling stop mechanism; of a pair of spaced standards arranged within said frame below the harness, a pair of plates adjustably mounted on the upper ends of said standards and inclined upwardly therefrom, the uppermost ends of said plates terminating in bearings, a longitudinal shaft mounted to oscillate in said bearings, arms adjustably connected to the ends of said shaft and extending laterally therefrom, the outer ends of said arms being offset and provided with bearings, angular rods adjustably carried in the bearings of the last mentioned arms, and vertically extending arms adjustably engaged with the angular rods, said last mentioned arms having portions thereof arouately designed and terminating in hook members for engagement with the weft fork of the filling stop mechanism.
